' Application April 22, 1953, Serial No. 350,459

1 Claim. (21. 15-434 This application relates to marking devices andmore particularly aims to provide a marking device which is primarily ashipping container of conventional glass hottle form, but which may beequipped with an inexpensive nib construction enabling it to be used asa marking device.

A feature of the present device is that the nib construction is soformed as to provide a completely satisfactory seal for the openshipping container or bottle whereby the device is instantly useful atany time despite long periods of non-use.

Still another feature of the present construction is the forming of allparts of the device, except the bottle and its packing, in a unitary capand nib assembly which can be transferred from an empty bottle to afresh bottle so as to transform a new bottle of ink, not equipped with anib, into a marking device.

A more complete understanding of the device will be obtained uponreference to the following specification in which Fig. l is an elevationview of the device partly cut away; Fig. 2 is a transverse section as ifon line 2-2 I of Fig. 1.

Referring to the drawing, it will be observed that it shows, a greatlyenlarged scale, a marking device which is really a combined ink bottleand pen. The bottle itself is an elongated open top glass ink bottlewhose ratio of length to diameter is very large, approximately three toone, whereby the bottle can conveniently fit in the hand of the user toform the handle of a marking device. The bottle is formed with a screwthreaded neck 11 and contains a packing 12 known in the trade as a feltpack but as often as not made of packing material other than felt, suchas a block of sponge rubber, twisted into the bottle and providing airflow around it.

Ordinarily such a bottle is sealed and any suitable seal or cover or capfor such bottle may be utilized. One well-known cover or cap for suchbottle is a sealing disc which is adhesively secured to the upper edgeof the bottle and which is readily puncturable to open the cover or sealand thus enable the bottle to be used with the unitary cover assemblynow about to be described.

Such assembly is a combined cap and nib unit and comprises a flatannularly flanged thin sheet metal cap 20 whose flange 21 is formed withthreads to enable the cap to be threaded onto the threaded neck 11 ofthe bottle. Loosely fitted into a center hole 22 of the cap is a verythin sheet metal nib holder 23 of ferrule form and of considerably lessdiameter than the cap. Within such holder is a nib 24 commonly known asa felt nib but which may be of any suitable material, felt at thepresent time being preferred. The nib 24 is firmly seated in the holderand projects above and below it as indicated. The nib is of flat barform and is pressed into the holder which is of circular form so thatthe holder tightly grips and holds the nib firmly in place and at thesame time provides air passages 25 in the holder alongside the nib. Aslip cover 26 of any suitable material such as plastic is detachablysecured by friction Lil to the holder 23 to cover the nib and preventevaporation of the ink through such nib and also to seal hole 22 forholder 23 by engaging cap 20 as shown.

The pack 12 in the bottle is in constant nib-wetting contact with thelower end of the nib projecting below the nib holder.

The nib holder has a rear portion in the form of a flared lip 28. Withinthe cap 20 is a gasket 29 positioned against such lip. The edge of thebottle neck, when the cap 20 is screwed down tight onto the bottle neck,is firmly in contact with the gasket whereby the bottle is sealed by thegasket. In addition, the bottle presses the gasket firmly against thelip of the holder and thus firmly presses the holder against the capwith the net result that the nib, which is firmly secured in the holder,is thereby firmly held with respect to the bottle. Thus the nib will notmove with respect to the bottle when the latter is used as a handleduring the Writing operation.

The gasket is of semi-hard but compressible material, preferably of aplastic material. The material is carefully selected to enable thegasket to function as a seal for the bottle when the cap 20 is threadeddown tight and also to enable the gasket to transmit thrust from thebottle to the lip of the holder and thus clamp the holder firmly in thecap. Any person skilled in the art, with this information, can selectthe particualr gasket material to be used.

I will be observed that the device herein shown is a satisfactorymarking device, but is also satisfactory commercially in that itcomprises an inexpensive shipping container and an extremely inexpensivenib construction applicable to a bottle while at the same timepreserving the desirable chracteristic of the pen being instantly usefulfor marking despite long periods of non-use, and without excessiveevaporation from the bottle through the felt pack and the nib providedthe cap 29 be firmly in place and the slip cover 26 likewise be normallyin place.

The sub-assembly comprising the cap 20 and the parts secured theretoincluding the gasket 29 may be removed from an emptied bottle to a freshbottle. The latter may have a seal to be punctured or may have a cap tobe removed but in either case, once the new bottle is prepared for thereception of the combined cap and nib unit, such cap and nib unit may beremoved from an old bottle and applied to the new one to convert anordinary shipping container into a marking device.

It is of great importance that the gasket be provided for the variousfunctions described herein, namely, to seal the bottle, and to enablethe bottle to clamp the nib firmly in place with respect to the bottle.
